TV always stays on Channel 2 or 3
If your TV remains continuously on 2 or 3, it is likely that the other channels are deprogrammed in the TV's memory. To reprogram them, check whether your remote control or TV set has a button marked PROG, AUTO-PROG, SCAN or AUTO-SCAN. Otherwise, refer to the owner's manual for your TV for more information.

What is the CATV function?
Most TVs have the CATV function (Cable Access TeleVision) , which changes the tuning mode on your TV set. A TV not connected to cable must be tuned in antenna or air mode. A TV connected to cable must be tuned in cable or CATV-STD mode.

Following a power outage or a procedural error, your TV may lose its initial programming and automatically reset to antenna, which is the default mode. In such cases, your TV will detect only Channels 2 to 13 (or 15). The other channels will be missing or all mixed up. This is not a cable problem but simply a minor adjustment that has to be changed on your TV.

CATV (no channels above 13 or 15)

Symptoms
The channels above 13 (or 15) are missing or all mixed up.

Problem with the sound
Your TV comes with certain functions that prevent any sound from being produced but do not affect picture quality. This is not a cable-related problem. If there is no sound on any of your channels but you are getting a good picture, the cable cannot physically be the problem.

Symptoms
If it's an SAP problem, there will be no sound on any or most of the channels.
The picture is excellent on all channels.

Possible solutions

• Check the volume level.
• Check whether the mute function is on.
• The SAP function (Second Audio Program) may have been turned on. To turn it off, check whether your remote control has an Audio or SAP button.
• Browse your TV menus until you find the SAP function, and then turn it off.
• In all cases, refer to your TV owner's manual.
• If none of these solutions works, contact your TV manufacturer's technical support service.
